Abstract

The invention provides an ocean buoy hydrodynamic characteristic analysis method based on a two-phase viscous flow theory. The method comprises the steps of taking a two-phase flow and incompressibleNavier-Stokes equation set as a basic control equation set, establishing a flow field mathematical model of the gas-liquid two-phase flow, correcting the flow field based on the reaction of the buoy to the flow field at the previous moment, and solving a wave field condition; based on the Newton's second law, establishing a motion equation of buoy gravity center; utilizing the two-phase flow mathematical model to calculate wave force and wave moment acting on the buoy body; solving the motion response of the buoy under the action of waves and the stress of the mooring system, and calculating to obtain the motion response of the buoy. Compared with a traditional non-coupling or quasi-static analysis method, the method has the advantages that a more accurate hydrodynamic characteristic analysis result can be provided while the calculation efficiency is ensured.

Description

technical field [0001] The disclosure belongs to the field of ocean engineering, and relates to a method for analyzing the hydrodynamic characteristics of ocean buoys based on two-phase viscous flow theory. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] my country has a vast ocean area, including a large area of ​​deep sea with a water depth of more than 400m and harsh sea conditions. The monitoring and development of this part of the sea is still in its infancy. The buoys placed in this area need to work under complex and harsh marine environmental conditions such as wind, waves and currents, and the hydrodynamic load and motion response of their structures are relatively complex. The monitoring buoy floats on the water surface, vibrating up and down and shaking sideways. When the buoy vibrates up and down, the equipment on the buoy, ...
